401(k) Employer Match Explained

Understand common 401(k) employer-match structures, vesting, contribution choices, and the questions to ask about your workplace plan.

Quick answer: An employer match is a plan contribution an employer may make based on an employee's eligible contributions, subject to the plan's formula, limits, and vesting rules.

Match formulas vary

An employer might match a percentage of what you contribute up to a stated threshold, use a different formula, or offer no match. Your plan documents—not a generic example—control the actual benefit.

What is vesting?

Your own salary-deferral contributions are yours, while some employer contributions can be subject to a vesting schedule depending on plan rules. Understand what happens if employment ends before full vesting.

Do not confuse match with contribution limits

Employee deferral limits and overall plan limits can change over time. Check current IRS guidance and your plan administrator rather than relying on an old dollar amount.
